**On the FT-890, FT-980, FT-990, FT-1000 and the FT-1000D, you should also jumper Pin #2 and Pin #5 to Ground.
**On the FT-847, FT-920, FT-950, FT-1000MP, and FTDX5000 you should also jumper Pin #5 to Ground.
Speaker audio and power are available on some models. Check your radio manual for availability of these signals and add the appropriate jumpers.

Power is not available on this connector, so you will need to use external power for the SignaLink Model SL-1+.
**On the FT-920, the AFSK/FSK switch MUST be set to AFSK, and you must be in "Data" mode (push the front panel "Data" button). The Mic Gain control appears to affect the operation of the Packet jack, so we suggest setting this to 50% and then adjusting as needed..
**The FT-1000MPMKV and FT-1000MKV Field MUST be in "Packet" mode (NOT usb!) for digital operation. For PSK31 or other "USB" digital modes, you'll need to set your radio's "User Mode" (selection 8-6) to "PS31U". This will configure the radio to look at the Packet jack and use the correct side band for PSK31. For more detailed information on this (including settings for other modes), see "Digital Modem Operation" in your radio manual.
**The 5-pin DIN jack on this radio supports only FM and LSB, which are not compatible with the majority of digital modes. We recommend connecting the SignaLink to the Mic jack instead.
##Detailed setup information for this radio is now available thanks to Wade Bolling, W5ERX. Please click here for details.

FT-8900R / Notes
For special signals requiring un-filtered "discriminator" audio, you will need to move the "SPKR" jumper to pin #4 (9600 baud output). Note that some newer radios do NOT provide this output, so this may not apply to your radio.
Power is not available on any 6-pin mini DIN Data Port, so you will need to use external power for the SignaLink Model SL-1+.
**FT-450 - Some users have reported that this radio has a very sensitive Data Port, making power adjustments with the SignaLink USB's TX knob somewhat touchy. If this is the case with your radio, then please click here for a simple solution to this problem.
**FT-950 - Some users of this radio have reported that the Notch Filter is turned on after a hard reset. If you see a "hole" in your waterfall display, then please make sure that your Notch Filter is turned OFF.
**The 6-pin mini-DIN Data Port on this radio supports FM and LSB only. It may also function only on VHF (not HF). Because of this, we recommend using the Mic jack instead, or the Data I/O jack on the FT-847 (see below).

FT-847 ONLY - 3.5mm Stereo "Data I/O" jack (use SLUSBNC, SL1+NC or SLCABNC)

For the FT-847, we recommend that you attach the SignaLink to the "Data I/O" jack. This jack works
for all modes and will let you keep your microphone plugged into the radio. We do not stock a cable for this
jack however, so you will need to build your own using one of our un-terminated radio cables (p/n SLCABNC).
The picture below shows how to wire this cable and install the jumper wires.

NOTE: The values shown below for R1 and C1 have been used for years in a number of our products.
You can use these values, or those shown in the FT-847 manual. Both will work just fine.
